Definitions
- the present invention relates to a new cosmetic composition capable of combating and preventing the effects of air pollution on the skin containing two plant extracts: Camellia sinensis and Lampsana commuais.
- the skin of a surface of approximately 2m 2 is the largest organ of the body. Indispensable to life, a real interface between the body and the environment, it is an interactive barrier. She has great coping skills or reactions to aggression. It is also a privileged site for the absorption of pollutants from the environment, with passage of substances that can have a direct cutaneous toxic effect.
- Clean air is a mixture of 78% nitrogen, 21% oxygen, 0.09% argon, 0.1% water vapor and other more or less rare gases including carbon dioxide, hydrogen , ozone.
- Air pollution is defined by the modification of clean air, by modification of its components, or by addition of harmful elements. Very schematically, it is possible to consider that the pollutants currently listed are mainly produced by industry, heating and automobile traffic. It is usual to classify them into seven chemical families:
- oxidizing agents such as ozone or nitrogen oxides are irritating and generate free radicals.
- Dusts are suspended particles sometimes fixing polycyclic hydrocarbons. Their harmful role is modified by the temperature and the degree of humidity of the air, the acid particles are irritating; there is a decrease in the hydration and oxygenation of tissue.
- organic chemicals are carcinogens, they come from industry waste and car combustion. - carbon monoxide causes tissue hypoxia, it comes 80% of cars.
- hydrocarbons and solvents represent 50% of automobile pollution, they are toxic, irritating, carcinogenic and mutagenic. In the presence of light, they react with nitrogen oxides and produce ozone.
- - Sulfur dioxide is one of the products of the combustion of oil and coal, it causes an alteration of the hydro-lipid film and irritation.
- - metals such as lead, zinc, aluminum, mercury, ... can interfere with cellular metabolism, by attacking enzymatic reactions. They participate in oxidative damage with DNA damage and cellular lipids.
- the effects of pollution on the skin are varied: there is an acidification of the cutaneous pH, a decrease of the hydration with increase of the transepidermal loss in water, an increase of the desquamation, a decrease of the horny flexibility, a modification of the surface lipids by the action of free radicals, a decrease in cellular energy metabolism.
- the repetition of these aggressions initiates an inflammatory process and predisposes to the reactions of intolerance.
- a cosmetic composition capable of combating and preventing the effects of air pollution on the skin must be able to combat these various phenomena.
- the invention therefore particularly relates to a composition containing an extract of Camellia sinensis and Lampsana communis.
- Camellia sinensis also called white tea is native to Southeast Asia, the variety used in the composition according to the invention is Pa ⁇ Mu Tan. It belongs to the tea family as well as green tea or black tea. It is distinguished from these other qualities by its preparation which is limited to minimalist operations allowing him to maintain its high content of polyphenols.
- the Camellia sinensis extract used in the composition according to the invention is obtained by hydro-glycolic extraction of white tea leaves. This gives a translucent solution of dark orange color and characteristic odor. This solution is titrated in total polyphenols and in OPC (proanthocyanidic olygomers); it has the following analytical characteristics:
- the Lampsana communis family Asteraceae, is a widespread annual plant, growing along roadsides and other sites subject to air pollution. It is a non-demanding plant and very resistant.
- the Lampsana extract used in the composition according to the invention is obtained by hydro-glycolic extraction of the aerial part of the plant. This gives a clear brown liquid with a characteristic odor having the following analytical characteristics: - water content: 18 to 26%
- composition according to the invention contains:
- Lampsana extract commuais 0.05% by weight Lampsana extract commuais.
- compositions according to the invention may also comprise one or more formulating agents or additives of known and conventional use in cosmetic and dermatological compositions such as, by way of examples and in a nonlimiting manner, softeners, colorants, film-forming active agents, surfactants, perfumes, preservatives, emulsifiers, oils, glycols, vitamins such as vitamin E, UV filters, etc.
- formulating agents or additives of known and conventional use in cosmetic and dermatological compositions such as, by way of examples and in a nonlimiting manner, softeners, colorants, film-forming active agents, surfactants, perfumes, preservatives, emulsifiers, oils, glycols, vitamins such as vitamin E, UV filters, etc.
- compositions according to the invention can be present in any form known to those skilled in the field of cosmetology and dermatology with no other pharmaceutical restriction than the application on the face and body.
- the compositions according to the invention are in the form of a gel, a lotion, a cream, an emulsion, a milk, a spray, etc.
- the present invention also relates to the cosmetic use of a composition according to the invention for combating and preventing the effects of pollution on the skin.
- the present invention also relates to the use of extracts of Camellia sinensis and Lampsana commuais, for the preparation of a cosmetic composition for combating and preventing the effects of pollution on the skin.
- the present invention finally relates to a cosmetic care method for combating and preventing the effects of pollution on the skin, characterized in that a suitable amount of a composition according to the invention is applied to the skin.

The results are expressed in nmoles per million cells per minute.
- the keratinocyte cultures are established from skin of human foreskins harvested during circumcisions and are amplified in KGM2 (Clonetics) medium supplemented with insulin, I 1 EGF and pituitary extract. The tests were carried out on keratinocytes between the 2 nd and 4 th passage, to ensure reproducibility between different experiments.
- the exhaust gases were produced by an engine.

- the addition of different amounts of the product in the tank of the oxygraphe shows a possible stimulation or inhibition of respiration.
- the amount of dissolved oxygen in a medium incubation was determined using a Clark electrode. Oxygen diffusing through a teflon film is reduced at the level of the platinum cathode polarized at -0.8 volts. Under these conditions, the current passing between this cathode and the silver anode is proportional to the oxygen concentration in the solution.
- the ion bridge is provided by a solution of half saturated KCl. The acquisition and the processing of the measurements are done on a microcomputer. Constitution of the lots:

- the amount of basal and newly synthesized ATP in the different aliquots is measured through the light emitted during the following ATP consumption reaction:
- I 1 ATP monitoring reagent ATP Bioluminescence Assay Kit HS II
- RLU relative unit of brightness
- the synthesis rate of ATP is expressed in nmol / min / 10 6 cells.
- Keratinocytes in culture were cultured, in a CO 2 oven, at a rate of 10 6 per run in an ADM culture medium (Clonetics).
- the treatment involves directly applying the complex Camellia sinensis and Lampsana coimunis to the desired concentration on the cells in suspension in the tank of the oxygraphe.
- the cells at a concentration of 10 6 cells / ml are suspended in a "respiratory buffer" (Hanks-Hepes glucose 20 mM), in the vat of the oxygraphe thermostated at 30 0 C and stirred.

- This assay was performed on whole non-permeabilized cells in the presence of glucose.
- the Camellia sinensis and Lampsana communis complex incubated at different concentrations with the keratinocytes previously exposed to the exhaust gas, induced a significant effect on the ATP mitochondrial synthesis rate at concentrations of 0.025 and 0.05%.
- the mitochondrial ATP synthesis rate increases by 19 and 29% respectively (FIG. 6).
- Camellia sinensis and Lampsana communis complex is active at very low concentrations, a sign of the synergy between the two extracts.
